NUTRITIONAL COMPOSITION AND ANTIOXIDANT CAPACITY OF METHANOL LEAF EXTRACTS OF Corchorus olitorius AND Telfairia occidentalis

Abstract

Vegetables possess both nutritional and medicinal properties and are daily consumed as food in form of beverages or health supplement. The aim of this study is to compare the medicinal and food values of two vegetables ( Corchorus olitorius and Telfairia occidentalis) . The following parameters were determined, these are; proximate, minerals, antioxidants, and phytochemicals (secondary metabolites) compositions. Results revealed that ash, fat and carbohydrate contents were higher in Corchorus olitorius ( 21.67% , 12.67% and 46.93% respectively). Telfairia occidentalis contained higher amounts of moisture and crude fibre contents (11.89% and 4.55% respectively). The mineral analysis showed that potassium had the highest value (1715.69mg/100g), sodium (49.62mg/100g), calcium (33.43mg/100g), iron (16.78mg/100g), manganese (9.44mg/100g), magnesium (4.39mg/100g), zinc (2.94mg/100g), copper (2.11mg/100g) and lead had the least value (0.21mg/100g). The antioxidant activity revealed that standard ascorbic acid had higher antioxidant activity values for TAC, reducing power, hydrogen peroxide and DPPH, where p
